Search engine Keyword frequency

[AndyN]

Hello (first post this)

Where can I find out some decent stats on what people search for? for example, if I have a retirement website, and want to find out how many search terms and keywords contain the word 'retirement'? I have found a useful page which tells me such info on overture, but I wanted something a bit more substantial/in depth, which includes more search engines, or at least google/yahoo and a breakdown into different counties (or at least UK searches). Does such useful software exist?

the search volumes are going to be off for various reasons:
-wordtracker has a small search userbase and extrapolates out errors
-overture has automated bots such as bid checkers scouring their partner network
digital point offers a free tool which compares the volumes from the two above side by side http://www.digitalpoint.com/tools/suggestion/

additionally Dan Thies also offers a keywords research service which breaks the traffic estimates down by engine. http://www.seoresearchlabs.com/keyword-research.php
